This course is an introduction to the non-perturbative bootstrap approach to Conformal Field Theory and to the Gauge/Gravity duality, emphasizing the fruitful interplay between these two ideas.
1. Conformal field theory - Conformal transformations, conformal algebra, local operators (primaries and descendants),
correlation functions, stress tensor, Weyl invariance, conformal Ward identities, Radial quantization (state-operator map),
unitarity bounds, operator product expansion, conformal blocks (Casimir equation), conformal bootstrap, conformal
anomaly, embedding space formalism, large N factorization.
2. Anti-de Sitter spacetime - Geometry, particle dynamics, free fields in AdS, interacting fields in AdS.
3. The AdS/CFT correspondence - quantum gravity as CFT, semi-classical limit and the large N expansion, the role of
String Theory, black holes and thermodynamics, universal long range forces, entanglement entropy.
